Abstract

The invention relates to a method for conversing PPT into video. The method comprises the following steps of processing each PPT frame in a PPT file: S1) confirming the complexity thereof according to the cartoon type of PPT frame, S2) setting a playing speed according to the complexity and playing the PPT frame with the set playing speed, performing the operations of sectional drawing and encoding on PPT frame during playing, automatically regulating the playing speed according to the time for sectional drawing and encoding after finishing the operations of sectional drawing and encoding, and S3) storing the encoding result into a video file. The invention further relates to a system for conversing PPT into video, comprising a cartoon type confirming unit, a playing and processing unit and a video generating unit. With the technical scheme, the invention can be applied to various machines, can fully utilize the machine resource to rapidly finishing conversion, can increase the conversion speed and ensure the conversion quality.

Description

technical field [0001] The present invention relates to video conversion technology in the field of multimedia, more specifically, to a method and system for converting PPT to video. Background technique [0002] The current method of converting PPT (Powerpoint) to video is to play the specified PPT file by calling the PPT program, take a screenshot of the played form, save the screenshot data into a temporary file, and then read the screenshot data from the temporary file. Encode and convert to various video files. The conversion speed of this method is slow, and the PPT file needs to be played completely once, and the information obtained from the screenshot is saved as a temporary file, and then the image of each frame is restored through the temporary file and converted into a video file. Moreover, in the case of tight system resources or low machine configuration, better conversion quality cannot be guaranteed. The playback process and playback rate of PPT files canno...
